Coinstar's fourth-quarter profit fell 27 percent due to poor performance at its new ventures. It forecast disappointing earnings ahead, and its shares tumbled in after-hours trading Thursday. The company owns the Redbox DVD kiosks and its namesake coin-counting sites.

Among the things sure to help shape the week ahead on Wall Street, Visa will tell us whether we've been choosing plastic over paper; Disney will tell us how much magic it has in its financials; and Panera and Chipotle will serve up their quarterly results.

Companies can do brilliant things, but there are also times where they fall flat on their faces. Sometimes CEOs can save the day, but at other times, they say and do the darndest things. There were plenty of winners and blunders this week: These were my favorites.

In a single deal, Amazon has become a legitimate rival to Netflix. Its streaming deal with EPIX gives its Amazon Prime customers free access to 2,000 movies from Paramount Pictures, MGM, and Lionsgate -- films like Iron Man 2, Super 8, True Grit, Rango, and many others.

There were a few positives in Netflix's quarterly report Tuesday, but the stock fell 14% thanks in part to mixed results and uninspiring guidance. But the real reasons investors fled are more complex -- and disturbing.

DVDs -- and even their more modern Blu-ray siblings -- are gradually fading to black, as VHS and LaserDisc did before them. Movie studios have seen this coming for some time. Problem is, it's part of a bigger trend they may not be able to overcome.

Verizon and Coinstar are joining forces in a new Internet streaming video venture built around Redbox's DVD-rental kiosks. Details are sketchy so far, but it will bundle streaming and DVDs, and it'll probably cost less than dominant player Netflix's service.

The boneheaded move of the week was committed by financial journalists, who collectively decided to blame Netflix's recent price hike for its reduction in subscriber targets -- a bad call indeed. Other head-scratchers included the end of boastful Fidelity Magellan chief Harry Lange's tenure, Cracker Barrel's attempts to evade Biglari Holdings, and Restoration Hardware's IPO.

Walt Disney is increasing the wholesale prices it charges for DVDs to movies-by-mail leader Netflix and movie-rental kiosk operator Redbox. Disney is looking to benefit further from being the only major studio to sell DVDs to the companies for rental the day they go on sale to the public.

Netflix, whose DVD-by-mail service hastened the demise of several video rental chains, may soon find itself under siege from Amazon. The world's largest online retailer appears to be on the verge of launching its own unlimited movie and TV-show streaming service.

Will the stubbornly high unemployment rate fall at all? We'll find out whether when the January employment reports come out this week. Also worth watching for are a host of earnings reports, led by economic bellwhether UPS. The package deliverer is expected to post strong results.

It's easy to blame Blockbuster's collapse, which culminated Thursday in a voluntary Chapter 11 filing, on the rise of streaming Internet video and kiosk rental options. But Netflix faced the same threats and it's thriving. So what did Netflix do smarter than its bankrupt rival?
